Integer quantum Hall effect in gapped single-layer graphene
(Amer Physical Soc, College Pk, 2012)
Analytical expressions for the Hall conductivity sigma(yx) and the longitudinal resistivity rho(xx) are derived in gapped, single-layer graphene using linear response theory. The gap 2 Delta, described by a mass term, is ...
Assessment of arsenic and mercury contamination in the Tisa River sediments and industrial canal sediments (Danube alluvial formation), Serbia
(Taylor and Francis Inc., 2012)
The purpose of this study was to examine the levels of As and Hg and mobility of these contaminants in the sediments of the River Tisa and canal sediments (alluvial formation of the Danube River, Serbia), in order to ...
Investigation of the morphology and surface properties of crosslinked poly(urethane-ester-siloxane)s / Ispitivanje morfologije i površinskih svojstava umreženih poli(uretan-estar-siloksana)
(Association of Chemical Engineers of Serbia, 2012)
Two series of crosslinked poly(urethane-ester-siloxane)s were synthesized from α,ω-dihydroxy-(ethylene oxide-poly(dimethylsiloxane)-ethylene oxide) (EO-PDMS- -EO), 4,4'-methylenediphenyl diisocyanate and Boltorn® hyperbranched ...
Modeling of kinetics of pertechnetate removal by amino-functionalized glycidyl methacrylate copolymer
(Springer Verlag, 2012)
Technetium-99 comprises a significant health risk, since edible plants can bioaccumulate and convert it to more lipophilic species that cannot be excreted through urine. Batch kinetics of pertechnetate removal from aqueous ...
Platinum(II/IV) complexes containing ethylenediamine-N,N '-di-2/3-propionate ester ligands induced caspase-dependent apoptosis in cisplatin-resistant colon cancer cells
(Royal Soc Chemistry, Cambridge, 2012)
Several new R(2)eddp (R = i-Pr, i-Bu; eddp = ethylenediamine-N,N'-di-3-propionate) esters and corresponding platinum(II) and platinum(IV) complexes of the general formula [PtCln(R(2)edda-type)] (n = 2, 4) were synthesized ...
Formation of Disperse Silver Deposits by the Electrodeposition Processes at High Overpotentials
(Esg, Belgrade, 2012)
In this study, electrodeposition of silver from nitrate solution at the high overpotentials was analyzed. Morphologies of silver deposits obtained at the different overpotentials and with the different electrodeposition ...
Mechanical and thermal properties of UV cured mixtures of linear and hyperbranched urethane acrylates
(Elsevier Science Sa, Lausanne, 2012)
The properties of urethane acrylate resin mixtures based on the linear and hyperbranched aliphatic polyesters were examined. Linear polyester was synthesized from neopentil glycol and adipic acid. Hyperbranched polyester ...
Al,Fe-pillared clays in catalytic decolorization of aqueous tartrazine solutions
(Elsevier, 2012)
In this work Al,Fe-pillared clays (PILCs) were applied as heterogeneous catalysts in catalytic wet peroxide oxidation of tartrazine azo-dye in water. A series of We PILCs with different Fe3+ content were synthesized. The ...
Improved synthesis and in vitro study of antimicrobial activity of α,β-unsaturated and α-bromo carboxylic acids / Optimizacija sinteze i in vitro proučavanje antimikrobnog dejstva α,β-nezasićenih i α-bromkarboksilnih kiselina
(Serbian Chemical Society, 2012)
A series of α,β-unsaturated and α-bromo carboxylic acids were identified as potent antimicrobial agents. The antimicrobial activity was evaluated using the broth microdilution method. All acids 1-12 exhibited a significant ...
Characterisation of New Bacillus circulans Strain Isolated from Oil Shale
(Croatia : University of Zagreb, Faculty of Food Technology and Biotechnology, 2012)
A new strain of Bacillus sp. was obtained during experiments of oil shale demineralization, which were carried out in order to get 'pure' organic matter (kerogen). The demineralization efficiency of newly isolated strain ...
